Status: offline 		tande,

I subscribe to Hobby Peoples online sales web alerts and they notified me on 7/17 about the big sale on the RDS8000 with 2 receivers. It kinda looks like the various distributors where getting them at different times to offer for sale because when I checked on Towers web site the day after I got the alert from HP they had no mention of the special sale yet. I'm not sure if anyone can give you a definitive day that the sale started to the public, maybe Mike can??

I'm wondering why you seem to be having some confusion on this sales special??

Status: offline 		It is up to the individual dealer to set prices and promotions for what they sell. We cannot tell them when to start or stop the promotion nor exactly what to sell it for. Hobby People went live with it about the 17th for example. But if you look through this thread, you will see some dealers started the promotion earlier than that.

Remember that only the retailer can set an actual price, etc. Telling people what they have to sell something for, etc. is price fixing. Even Mc Donald's don't all have the same prices! (go to the local Mall here or to any airport and you'll see that the menu prices are different, etc..)

Sorry, I was just trying to figure/out if this was the same kind of promotion that "Spektrum" offered awhile back-I see now that it's not-

Status: offline 		Hello, I've enjoyed this thread and am impressed with the support given by Airtronic exectutives. I could not decide to go with spectrum, futaba or airtronics. After months of reading, I am ready to buy this tx w/ the 2 rx's and have a question about using the Phoenix simulator. Which cable do i buy from Phoenix to use with this tx. I want to fly both helis and planks. Thank you.

Status: offline 		The RDS8000 with bonus receiver is now on the Tower website. I found it in the Just Announced section. It was added July 21, but it is pending availability

This has got to be one of the best deals ever...... With this, there is no reason not to leap into the 2.4 GHz arena. I have been flying my RDS for about two months with no problems. I needed to change the end point on throttle yesterday. No need for a manual....I had it changed it 2 minutes but just scrolling through the channels and then down to Endpoint.

I would buy another of these, but will wait for the 10 channel....but it is awful tempting.....

Status: offline 		I made several successful flights this morning in what could be considered an "acid test" of the 2.4 system. The radio was flown in a SAM old timer model with spark ignition engine. For those not familiar, the ignition system in these models has no noise suppression whatsoever. No resistor plug, no shielded hi-tension lead, no self contained magneto. It's a brutal RF environment in which many of the FM systems can't function at all. This particular airplane had been plagued with noise no matter what brand of receiver I tried, spacing between components, etc. I had used every trick of 30 years' experience to make the FM installation workable. Then, like magic, the 2.4 systems hit the market. All I did was swap in the new receiver and my problems disappeared.

At this point I think I will retrofit all my ignition airplanes with RDS receivers and put this noise issue behind me once and for all.

Status: offline 		I want everyone to be careful, yes RF is reduced to not existent with 2.4 but I have experienced significant RF from an ignition system rendering my RDS useless. The RF was from a DZY twin ignition unit, which I have since swapped out for a C.H. unit with great success. Nonetheless, 2.4 systems are not bullet proof but they are much better than 72MHZ and I love my RDS.

Status: offline 		Many electronic companies who make electronic accessories do not test their equipment's RF output to see if they meet FCC standards and/or if they create excessive RF in any of the active RC Frequencies world wide. 27, 35, 36, 40, 41, 72, and now 900 and 2.4...

So, yes, 2.4GHz is just like any other radio. If overwhelming RF in the same frequency range is being emitted, you'll experience radio problems. It's that simple.

In MANY cases, the electronic noise is in the 100MHz and below range, thus 2.4GHz would not be affected much or at all.

Anyway, that's why a range test is important. Another thing I kinda' preach is a power-on range test. Engine/Motor RUNNING while the range test is made (so 1 range test power off and then the next power on). This is a GREAT way to ensure there is not a problem. There's another post about turning the model in different directions to ensure the antenna placement doesn't have any "dead" spots. It takes 2 people, but it's a pretty easy test. I re-posted it at my blog. mikegoesflying. wordpress. com (remove spaces).

What we see is "most" electronic ignitions are no where near the 2.4GHz band. But there are a few electronic ignition with rf/harmonics that hit it.

Anyway, "metalmetal67's" advice is sound! Be CAREFUL and a power-on range test is a GREAT way to ensure everything is ok. But indeed 2.4GHz "generally speaking" is WAY less apt to get interference from typical equipment used in R/C planes/cars/boats...

Mike

PS. Glad everyone likes the promo and THANKS for all the kind words about us.

Status: offline 		Yes, I should have mentioned the "engine on" range test. This is pretty much a standard precaution for SAM fliers. In essence, one does a normal ground range test and notes the distance attainable. Then, without relocating or repositioning the model, the engine is started and a second range test performed. With FM systems, range degradation with engine runing may vary from nearly no reduction in distance to as much as 90%. As a rule of thumb, we usually accept up to a 25% reduction in ground range with engine running.

In this particular model, range loss with engine running was around 90%, thus it was not flyable. Lots of experimentation produced no real improvement as long as I used FM radios. With the RDS, I got 75 paces (~225 feet) engine off and 70 paces (~210 feet) engine on. This reduction is insignificant, and may have been no more than repeatability scatter between tests.

Status: offline 		I want to thank Mike Greenshields and Global Hobby for such an outstanding promotion on the RDS8000 W/ extra rx. I just ordered one tonight at Towers Hobby. I also contacted Phoenix simulator about an adapter. They assured me the adapter was in production and would be out soon. They stated thier RD adapter would not work with RDS. Also thanks to everyone who contributed on this thread. You folks helped me to make my decision along with Ken"s outstanding review. I am very excited to join the Airtronics family and am sure I'll be relying on this community for further help. I am 51years young and love this hobby. I'm interested in using this tx to learn heli's as well as fly planks.
